Pancreatic biopsy is often used as one of the methods for diagnosing pancreatitis. This manipulation is carried out when it is necessary to send living cells of the gland to a morphological study, in order to establish pathology more accurately on the basis of the results of the analyzes. For this, a puncture or excision-incisional method of pancreatic biopsy may be used. Its importance for establishing a differential diagnosis between chronic pancreatitis and a tumor can not be underestimated.
Puncture is carried out with special needles, Each needle has its own design features and is used for different methods of needle biopsy. So the needle of Trunin and Wim-Silverman is used for collet biopsy. Needles with a diameter of 1mm without sealing the biopsy channel or with it, are used for thick-needle biopsy. Thin needles are applied by aspiration with fine needle biopsy of the pancreas. A needle biopsy is used for fine needle puncture. At the end of his tube is a knife, which, when fired, quickly dissects the tissues and into the needle cavity, the material under study enters the thin column.
Excision of the tail and body of the gland can be applied only in the open way, at the time of surgery. The spinal is drawn along the anterior wall of the duodenum. Puncture biopsy of the pancreas is carried out only under local anesthesia, because when the tissue is pierced, the patient has severe pain.
First, excision of the pancreas was performed only during the operation, but this method of diagnosis has a number of adverse consequences, and if a preoperative puncture biopsy is sufficient for an accurate diagnosis, the latter is preferred. With this method, the needle is driven into the pancreas, controlling the entire process with axial computed tomography and ultrasound.
Because biopsy refers to surgical methods of diagnosis, it is important to take into account all possible negative consequences: the formation of false cysts in the gland, the occurrence of bleeding in the pancreas, the development of peritonitis and pancreatic fistulas. Negative consequences in the work of an experienced specialist - a phenomenon fairly rare and occurs once in 60-80 cases. But jaundice and obstruction of the main bile duct is found in every fifth case, after resection of the gland head.
